    Thread Summary
    
                The user is trying to establish SPI communication between an Arduino Uno and an ADE7758 IC. The user has measured Vref at 2.42V and can read four register values, indicating that the SPI communication is likely working. However, when using an ADuM1402 digital isolator, the user only gets 0xFF outputs, possibly due to incorrect SPI clock settings or logic levels. The support engineer suggests verifying the SPI clock speed and logic levels with an oscilloscope and providing a schematic of the isolator connections.

    Hi, recently bought a ade7758. I am trying to enstablish communication between arduino uno and ade7758. 
    

    This is my first analog devices chip. I don't have experience on this. 
    

    I have already set up the schematic of datasheet (page 17 - a).
    

    Is there any method to understand if my communication working? Without AC connection. I am using 5V DC, And I am measuring Vref to gnd 2,42 V.
